Flying from Udon Thani to Hat Yai
In short
Getting from the North-East to the far south normally means a change in Bangkok. The exception is Thai Lion Air's nonstop from Udon Thani (UTH) to Hat Yai (HDY): about 1,191 km in a straight line and about two hours in the air. The airline flies it on selected days only, not daily, so check your dates in the search before planning anything around it.
At Udon Thani airport, 90 minutes before departure is usually plenty. The airport keeps roughly 06:00 to 22:00 hours and is small enough to cross in a few minutes. There is a paid Coral lounge in Terminal 2, but the better food is landside, in the first-floor buffet restaurant.
Checking your Thai Lion Air baggage allowance
Thai Lion Air sells several fare types, and the baggage allowance changes with each. Look at the inclusions on the booking page, and if you need more weight, add it online before the day.
Taxi counter and AOT Limousine at Hat Yai arrivals
Hat Yai International Airport lies 10 to 12 km south-west of the city. Transport is well organised:
- The taxi counter sits in the arrivals area between gates 7 and 8; the trip to the centre takes 20 to 30 minutes.
- The AOT Limousine desk sells fixed-price cars to Hat Yai addresses.
- The Airport Van runs to Sanamanusorn, Central Festival, Lee Garden Hat Yai and Kim Yong Market.
- The city minibus ends at Hat Yai Bus Terminal, handy for vans and buses onward.
Change money at the bank counter or an ATM rather than at transport booths, where rates are poor. Songkhla and Samila Beach are about 45 minutes away by car, and the Sadao crossing into Malaysia is roughly an hour south.
Hat Yai's wet months and an evening for its food
Hat Yai's wettest months are usually October to December, when heavy rain can slow the airport road. January to April is drier. Whenever you land, set aside an evening for the city's food: Hat Yai fried chicken, dim sum and the night markets are reasons in themselves to stay a night.
Udon's airport from 1932 to the Vietnam War
Udon Thani's airport has been in use since 1932. It belongs to the Royal Thai Air Force, and the Department of Airports manages the civil terminal. In the Vietnam War years it was Udorn Royal Thai Air Force Base, an American front-line base and the Asian headquarters of Air America. Alpha Jets of the air force's 231 Squadron still share the 3,048 m runway.
The airport handled 2,012,155 passengers in 2025 and 475 tonnes of freight.
Thai Lion Air's all-737 fleet
Thai Lion Air, part of Indonesia's Lion Air Group, flew its first service on 4 December 2013 and is based at Don Mueang. It operates only Boeing 737s, 28 in August 2025, split between the 737-800 and the 737-900ER. From Udon Thani it flies to Don Mueang, Hat Yai and U-Tapao, and from Hat Yai it also serves Don Mueang.
Hat Yai airport's growth and expansion plans
Hat Yai International Airport, run by Airports of Thailand, carried 3,305,661 passengers in 2025, up 6.7 percent. The terminal was designed for 2.5 million passengers a year and passed 4.5 million in 2018; plans aim to lift capacity beyond 10 million by 2030. The airport is about 43 km from Songkhla city, is reached by Highway 4135, and has a 3,150 m runway. Other domestic routes from Hat Yai include Thai AirAsia to Chiang Mai, Bangkok Airways to Phuket and EZY Airlines to Betong and Hua Hin.

How to book Udon Thani to Hat Yai for less
Three pointers for the flight south.
1,191 kmstraight-line distance
Book around the schedule, not the other way
Because the nonstop runs on selected days, fix the flight first and build hotels around it. If the days do not work, two flights via Don Mueang are the alternative.
1st floorATMs and bank exchange
Use the bank counter in Hat Yai
Transport booths in arrivals will change cash, but at poor rates. The bank counter and ATMs near the arrivals hall give a better deal.
06:00city minibus starts
Ride the minibus to the bus terminal
Heading on to Songkhla, Satun or the border? The city minibus finishes at Hat Yai Bus Terminal, so you avoid paying for a taxi twice.

Frequently Asked Questions (FAQs)
Getting there
Thai Lion Air is the only one. It flies the route on selected days, so search your dates to see when it operates.
About two hours for roughly 1,191 km, from Thailand's upper North-East to the lower south.
Ninety minutes is usually enough. Allow two hours on holiday weekends and during the Horticultural Expo, which runs until 14 March 2027.
Book a taxi at the counter between gates 7 and 8, buy a fixed-price car at the AOT Limousine desk, or take the Airport Van or city minibus. The drive takes 20 to 30 minutes.
At Sanamanusorn, Central Festival, Lee Garden Hat Yai and Kim Yong Market. It suits travellers staying in the centre with light luggage.
There is no direct bus. Take the city minibus or a taxi into Hat Yai and change, or book a car with a driver for the 45-minute run.
No. It opens at 06:00 and closes at midnight, so plan transport into town if your flight arrives late.
Timing & weather
Yes. The Sadao crossing is about an hour's drive south of the city, which is why many Malaysian visitors come through Hat Yai.
General
Hat Yai city and the airport are not covered by the UK's advice against all but essential travel, but several districts further south and the provinces of Pattani, Yala and Narathiwat are. Read your own government's advice before travelling beyond Hat Yai.
Hat Yai fried chicken, dim sum and whatever the night markets are cooking. Kim Yong Market and the streets near the clock tower are good places to start.
What's included
That depends on the fare type you choose. Check the inclusions before you pay and add extra weight online rather than at the airport.
